These are shows that never got to finish and left us wanting more.
  1. Firefly
    (Obviously) This is kind of the King of shows that were cancelled too early. Fortunately fans got a movie (Serenity) and several comic books to help ease the pain of their loss.
  2. Defying Gravity
    This ABC nighttime drama was poorly advertised as "Grey's Anatomy" in space. It was ultimately too soap opera-y for sci-fi fans and too sci-fi for the Grey's Anatomy crowd. It's compelling story was never resolved but the show'a creator later divulged its secrets in interviews when it became clear that no one was going to save it.
